***SECOND EDIT*** HAVE CONTACTED SELLER AND ARE SENDING REPLACEMENT. WILL DO ANOTHER UPDATE AFTER RECEIVING AND I SEE HOW IT DOES
**EDIT REVIEW *****
AFTER MY SECOND CHARGE MY SCREEN HAS GONE BLACK AND WILL NOT CHARGE ANYMORE. THERE IS NO WARRANTY CARD AND NO WAY TO CONTACT THE COMPANY EVEN THOUGH IT STATES ON AMAZON THERE IS A WARRANTY. I AM SO DISAPPOINTED BECAUSE I REALLY LIKED THIS WATCH*****
This tracker does all the latest features except the ECG. It seems to be very accurate. As long as you have your Bluetooth connected it automatically will take your blood pressure, pulse and oxygen every hour and record it in the app. There’s no having to press down on the watch to get it to operate. If you want to see it then just put it on whatever you want to test and let it set there.
